(Cl. 70-21) ABSTRACT OFTHE DISCLSURE A padlock incorporating both combination and keyactuatedmechanisms, employing a locking bolt engaging 'and locking a padlockshackle member against release. A gate vane member is pivoted on thelocking vbolt and abuts against combination discs to prevent unlockingmovement of the bolt. Alignment of gate notches in the combination discsto receive the vane member releases the locking bolt and the padlockshackle member and a key mechanism rotates the vane member out ofabutting position to release the locking Ibolt and shackle member.

This invention relates in general to locks, and more particularly to animproved padlock construction incorporating both combination andkey-actuated mechanisms.

Padlocks, as heretofore known, were usually constructed for operationeither by more or less conventional keyactu-ated mechanisms, orcombination controlled mechanisms. Such padlocks were excessivelycomplicated and expensive to manufacture, and lacked the desiredstrength, durability, and security.

It is accordingly a principal object of this invention to provide animproved padlock employing both combination and key-actuated mechanisms,by which such padlock can be alternatively operated either by acombination controlled mechanism or by a key-actuated mechamsm.

It is another object of this invention to provide a padlock mechanism ofimproved strength and security.

It is another object of this invention to provide an improvedkey-actuated padlock.

It is still another object of this invention to provide an improvedcombination operated padlock.

It is a further object of this invention to provide a padlock ofgenerally improved design, operating characteristics, and durability.

These and other objects, advantages .and features of novelty will beevident hereinafter.

Apparatus Referring rst primarily to FIGURES 2-7, the principalenclosing body elements and external components of the apparatus of theinvention are:

A hollow, drum-shaped lock case, shown generally at 10, comprising aninner, hollow, generally cylindrically-shaped, open ended, rigid metallock chassis 12; a generally cup-shaped, sheet metal inner case 14,closely fitting around the lock chassis 12 and having a circular frontopening 16 and a removable, disk-shaped, metal back closure plate 18; anouter, relatively thin, sheet metal cover 20, formed on the front sidethereof coaxially of said opening 16 with a slightly raised, annularescutcheon portion 28, with a coaxial circular dial opening 24 therein,and on the backside thereof having a relatively thin, sheet metal,disk-shaped cover 26, retained thereon by means of crimping the edge 20of sheet metal cover 20 around the back edge' of the disk-shaped cover26; a generally U-shapedy shackle y30, having a pair of parallel,shackle arms 32 and 34 which normally extend into the lock case 10through suitable shackle arm openings formed at 36 and 38 in the upperedge thereof; a combination dial 39, including a dial housing 40rotatably supported in and extending externally from the circularopening 16 in the front side of the inner case 14; and a key-operated,cylindrical lock 42, the outer key-slotted end 44 of which extendsthrough an aperture 46 in the outer end 48 of the dial housing 40.

Referring next in more detail to FIGURES 2 and 4-l0d, the lock chassis12 is formed on the interior thereof with an integral, inwardlyprojecting, shackle guide 50, having a shackle guide bore 52 extendingvertically therethrough and coaxially joining `at its upper end thebeforementioned shackle arm opening 38 in the upper edge of the lockcase 10. Vertically, slidably supported within the shackle guide bore 52is the inner end portion of shackle arm 34 of the shackle 30. The innerlower end portion of shackle arm 34, contained within the shackle guidebore 52, is formed with a flattened side 54 and on the lower end with astop knob 56 of the same outside diameter as the shackle arm 34 andjoined thereto by a short necked section 58 of reduced outside diameter.A stop pin 59 extending crosswise through the shackle guide 50 andintersecting the edge of shackle guide bore 52 adjacent its upper endand opposite the flattened side 54 of the shackle arm 34 serves to limitthe axially outward movement of the shackle 30 by engagement with theupper annular surface 60 of the stop knob 56. When positioned at itsextreme axially extended position, with the stop pin 59 in the shortnecked section 58 adjacent the upper annular surface 60 of the stop knob56, the shackle 30 may be rotated to any desired angular position aboutthe longitudinal axis of shackle arm 34.

The opposite shackle arm 32 of the shackle 30, when in the closed,locked position, as best illustrated in FIG- URE 2, extends into theupper edge of the lock case coaxially through the beforementionedshackle arm opening 36. The lower end portion of the shackle arm 32,which extends into the lock case 10 when the shackle 30 is in itsclosed, locked position, as shown in FIGURE 2, is formed with alaterally facing lock notch 62 adjacent the lower end thereof, havingopposite, upper and lower, laterally divergingly beveled surfaces 63 and64, and the lower end of the shackle arm 32 is formed with an inwardly,downwardly sloping projection 65, sharing the upper beveled surface 64of the lock notch 62, and bounded at the lower end thereof by beveledsurface 66, surfaces 64 and 66 being substantially parallel with oneanother. Fixedly attached to and extending perpendicularly inwardly ofthe back closure plate 18 is a bolt lever pivot pillar 68, and rotatablysupported in an opening 70 in the back closure plate 18 is a combinationdisk assembly supporting and key-actuating shaft 72, which shaft 72 andthe disk assembly supported thereon will be hereinafter more fullydescribed.

The rearward end of the bolt lever pivot pillar 68 is secured to theback closure plate 18 by means of a reduced diameter shank portion 76thereof, which is pressed through a chamfered hole in the back closureplate 18 and upset at its end as best shown at 78 in FIGURE 5. The boltlever pivot pillar 68 is formed with a base portion 80 of increaseddiameter, thereby forming a forwardly facing annular shoulder 82.Pivotally supported on the bolt lever pivot pillar 68, forwardly of theannular shoulder 82, is a generally L- shaped, locking bolt lever 84,the locking bolt lever 84 being provided with a bearing bore 86 adjacentits lower end, through which the bolt lever pivot pillar 68 supportinglyextends. The locking bolt lever 84 is retained on the bolt lever pivotpillar 68 by means of an annular retainer collar 88, setscrew-fixed tothe forward end thereof.

The upper, outer end portion of the locking bolt lever 84, is bifurcatedto form a pair of spaced-apart, parallel, supporting members, as bestshown at 90 and 91 in FIGURES 6 and 9, and such supporting members 90land 91 are provided with a pair of coaxial, pivot bearing holes 92 and93, for receiving opposite pivot ends 94 and 96 of an upper crossmember98 of a generally I- shaped gate vane member 100. The gate vane member100 is thereby pivotally suspended from the upper, outer end portion ofthe locking bolt lever 84, with freedom for limited angular swingingmotion. The lower end of the gate vane member 100 is formed with acrosswise-extending, rectangular shaped, gate dog 102 for engagementwith gate notches in combination disks, as will be hereinafterdescribed.

The intermediate portion of the locking bolt lever 84 is formed withshackle arm engagement means which includes a combined lock tongue 103and shackle arm receiving recess 104, said lock tongue 103 having upperand lower beveled surfaces 105 and 106 approximately matching in shapethe beforementioned beveled surfaces 4 63 and 64 of the lock notch 62 inthe shackle arm 32, and shackle arm receiving recess 104 having upperand lower beveled surfaces 106 and 108 respectively, approximatelymatching in shape the beveled surfaces 64 and 66 of the projection 65 onthe lower end of the shackle arm 32.

Pivotally supported upon and positioned against the rearward face of thelocking bolt lever 84 by means of a pivot stud 110, the shank of whichis pressed into a drill hole 112 in the lower portion of the lockingbolt lever 84 adjacent the bearing bore 86, is a vane catch lever 114.Torque is applied to the vane catch lever 114 relative to the lockingbolt lever 84 by means of a coil spring 116, which encireles a portionof the pivot stud 110, with the upper extremity 118 of the coil spring116 pressing against a laterally extending tab 122 formed on the pivotof the vane catch lever 114, and the opposite lower extremity of thecoil spring 116 pressing against the base portion 80 of the bolt leverpivot pillar 68, thereby urging the vane catch lever 114 to pivot in aclockwise direction relative to the locking bolt lever 84, as viewed inFIGURE 2. The outer end of the vane catch lever 114, opposite its pivotend, is formed with a downwardly facing, hook-shaped vane catch 124,which includes a laterally extending catch tab member 126. Thehook-shaped vane catch 124 is adapted to make hooking engagement downover the left-hand end of the gate dog 102 of the gate vane member 100when the padlock is in locked condition, as shown in FIGURE 2, and whenin unlocked condition, as shown in FIGURE 3.

As best shown in isometric FIGURE 9, the inner bearing end of thecombination disk assembly supporting and key-actuating shaft 72 has anintegral flange collar 130 formed with diametri-cally opposite flats 132and 134 which fit into a correspondingly shaped opening 136 formedthrough the central portion of a vane catch control cam carrier body140. The vane catch control cam carrier body 140 is formed with agenerally radially extending arm 142 which carries at its outer end atransversely extending foot member 128. The vane catch control camcarrier body 140 is also provided with a radially rising vane catchcontrol cam 144, which terminates in a radially extending end portion145, carrying a crosswise-extending control pin 146.

Coaxially supported upon the combination disk assembly supporting andkey-actuating shaft 72 is a tubular shaped, combination disk-supportinghub 148, having at its rearward end an integrally formed radial fiange150. A pin hole 152 is provided through the radial flange 150, whichmakes rotation-preventing engagement with a projecting pin 154 fixed inthe back closure plate 18. The hub 148 is thus rotationally fixedrelative to the back closure plate 18 and lock case 10, while at thesame time providing freedom for rotational movement of the shaft 72therein.

Coaxially supported upon the hub 148, between the forward end 156thereof and the radial flange 150, are the following components of thecombination disk assembly:

A spacer washer 158; a combination disk driver coupling member 160; afirst combination disk 162, having a gate notch 163 in the edge thereof;a first spacer ring 164; a second combination disk 166, having a gatenotch 167 in the edge thereof; a second spacer ring 168; a thirdcombination disk 170, having a gate notch 171 in the edge thereof; and aScrambler cam annulus 172, carrying a radially extending cam lobe 174.The first, second, and third combination disks 162, 166, and are freelyrotatably supported on the hub 148, 'but the first and second spacerrings 164 and 168 are nonrotatably supported on the hub 148, rotationbeing prevented by key pins 176 and 178 which project radially inwardlyfrom the bores thereof into axially slidable Ibut rotation-preventingengagement with a longitudinal key slot 180 formed in the exteriorsurface of the hub 148. The spacer rings 164 and 168,

being thus rotationally fixed with respect to the hub 148, serve torotationally isolate the several combination disks thereon, thereby, inoperation, preventing rotational movement from being frictionallytransmitted from one combination disk to the other.

The combination disk driver coupling member 160 is provided,intermediate its center bore and periphery, with an axially, rearwardlyextending drive pin 182, which engages a correspondingly located pinhole 184 formed through the first combination disk 162. The firstcombination disk 162 is also provided, intermediate its center -bore andperiphery, with an axially, rearwardly extending combination disk drivepin 186. The second combination disk 166 is similarly provided withcircumferentially spaced-apart, axially forwardly and rearwardlyextending combination disk drive pins 188 and 190, and the thirdcombination disk 170 is likewise provided with circumferentiallyspaced-apart, axially forwardly and rearwardly extending combinationdisk drive pins 192 and 194. All of the combination disk drive pins,except drive pin 194; namely, drive pins 186, 188, 190 and 192, arepositioned at equal radial distance from the centers of the combinationdisks 162, 166, 170, such that upon imparting rotation to thecombination disks 162, 166, 170 relative to each other by manipulationof the combination dial housing 40, the adjacent combination disk drivepins 186, 188, 190, 192 will be moved into driving engagement With oneanother, such as to enable the combination disks 162, 166, 170 to berotationally positioned, relative to each other on the hub 148, insequence and in accordance with a predetermined rotational angularrelationship, as is well known in the combination lock art.

The most rearward one of the beforementioned drive pins 194, carried bythe third combination disk 170, makes driving coupling engagement with apin hole 196 formed through the Scrambler cam annulus 172, whereby thecombination disk 170 and the Scrambler cam annulus 172 are rotationallyfixed together.

Referring again tothe combination disk driver coupling member 160, thiscoupling member 160is provided with four, circumferentially equallyspaced-apart, axially forwardly extending, ycoupling tabs 200, 202, 204and 206. One of the coupling tabs (for example, tab 200) is preferablywider than the others for the purpose of indexing it rotationally withrespect to a disk shaped, combination dial coupler member 208, the innerface of which is formed with four mating coupling sockets 210, 212, 214and 216, as best shown in FIGURE 7, for respectively receiving thecoupling tabs 200, 202, 204 and 206, the coupling socket 210 being thewidest, such as to receive the corresponding, widest coupling tab 200.The combination dial coupler member 208 is seated within acorrespondingly sized counterbore 218 formed in the innermost end of anannular boss portion 220 of the combination dial housing 40 and isretained therein and nonrotationally coupled with respect thereto, bymeans of a radial coupling pin 222, as best shown in FIGURE 5.

The spacer washer 158 is rotatably positioned on the reduced diameterouter end portion 224 of the combination disk supporting hub 148, withthe inner edge thereof in retaining abutment with the inner annularsurface portion of the combination disk driver coupling member 160 andwith the opposite outer surface thereof in retaining abutment with themarginal surface portion of the cornbination dial coupler member 208immediately surrounding t-he coaxial bore 226 thereof.

Pivotally supported on a pivot stud 228, pressed fitted into a hole 230,in the lower portion of the back closure plateV 18, is a Scrambleractuator lever 232. The Scrambler actuator lever 232 is provided at thepivot end With a bearing hole 234, through which the beforementionedpivot stud 228 extends, and at the opposite outer end thereof theScrambler actuator lever 232 is provided with the beforementioned,laterally extending, actuator foot 238. A spring retainer studv 236 isattached to an intermediate portion of the Scrambler actuator lever 232,and a Scrambler actuator spring 240 encircles a portion of the pivotstud 228, with one end portion 242 of the Scrambler actuator spring 240bearing against the adjacent inner surface of the lock chassis 12, andwith the other end portion of the Scrambler actuator spring 240 bentunder the spring retainer stud 236 and extending outwardly along theside of the Scrambler actuator lever 232 into bearing engagement with anotch 244 formed in the inner edge of the actuator foot 238. The extremeouter end of the Scrambler actuator spring 240, which extends beyond thenotch 244 in the actuator foot 238, is formed with a hook portion asshown at 246. In the operation of the apparatus as hereinafterdescribed, the hook portion 246 of the Scrambler actuator spring 240 isadapted to move upwardly over and make engagement with the upper end 175of the cam lobe 174 of the Scrambler cam annulus 172.

Referring next principally to FIGURES l, 6, 8a, and 8b, iixedeccentrically in a pocket 250, formed within the body of the combinationactuator dial housing 40, is the beforementioned conventionalkey-operated lock 42. The outer key slotted end 44 of the key-operatedlock 42 is exposed through the aperture 46 formed through the outer end48 of the combination dial housing 40 and is provided with a key slot252 for receiving a conventional key (not shown) for key operation ofthe key-actuated mechanism. Extending inwardly from the rearward end 254of the lock plug 42, and connected for rotation by the mechanismtherein, is a small externally toothed pinion gear segment 256, formedwith a flat, untoothed side portion, as best shown at 258 in FIGURES 8aand 8b. Upon rotation of the pinion gear segment 256, from the positionshown in FIGURE 8a to that shown in FIGURE 8b, the teeth 260 of thepinion gear segment 256 are moved from a position of disengagement, asshown in FIGURE 8a, into meshing engagement with teeth 262 of anannular, internally toothed gear 264, as shown in FIGURE 8b.

The internally toothed gear 264 is formed with an axially rearwardlyextending hub portion 266 which is rotatably supported within thecoaxial bore 226 in the combination dial coupler member 208. The hubportion 266 is provided with a squared central opening 268 which makesdriving coupling engagement withV a matching squared outer end portion270 of the combination disk assembly supporting and key-actuating shaft72.

As hereinbefore mentioned, the combination dial housing 40 is rotatablysupported within the circular front opening 16 formed in the inner case14 and such rotatable support of the dial housing 40 is accomplished bythe relatively short, coaxial annular boss portion 220 formed on itsinner end, which extends coaxially through and is rotatably supportedand retained in the circular front opening 16 by means of a thin, flat,annular, retainer snap-ring 272 which extends radially from a snap-ringgroove 274 formed around the exterior of the annular boss portion 220,to a position bearing upon the inner marginal surface of the inner case14 immediately surrounding the opening 16.

Operation The operation of the hereinbefore described lock mechanism isas follows:

When the padlock is in a normal, locked condition, the positions of theparts thereof are as shown in FIG- URE 2. Under such locked condition,the shackle 30 is in its fully retracted, closed position, with the locktongue 103 of the locking bolt lever 84 in engagement with the locknotch 62 of the shackle arm 32, and the projection 65 at the lower endof the shackle arm 32 is in engagement with the shackle arm receivingrecess 104. At the same time, the pivotable gate vane member is in thevertical position shown in FIGURE 2, with the lower end edge of the gatedog 102 thereof positioned adjacent to or in abutment with one or moreofthe peripheries of the combination disks 162, 166 and 170, one or moreof the combination disks being rotationally positioned upon the hub 148,such that one or more of the gate notches 163, 167 or 171 thereof is outof engaging alignment with the gate dog 102.

The gate vane member 100 is retained in such vertical position byhooking engagement of the vane catch 124 and vane catch tab member 126of the vane catch lever 114, over the right-hand edge of the gate dog102, acting under the force of the coil spring 116. The resultantabutment of the lower end of the gate dog 102 of the gate vane member100 with the peripheries of one or more of the combination disks 162,166 or 170 blocks any possible clockwise pivotal motion of the lockingbolt lever 84 about the bolt lever pivot pillar 68, thereby retaininglock tongue 103 in locking engagement with the lock notch 62 in theshackle arm 32 and the projection 65 at the lower end of the shackle arm32 in locking engagement with the shackle arm receiving recess 104 inthe locking bolt lever 84. Extension of the shackle 30 to its extended,unlocked position is thereby prevented.

When it is desired to actuate the padlock mechanism to an unlockedcondition, this can be accomplished in two separate ways; namely, eitherby key controlled actuation through operation of the mechanism of thelock 42 in the dial housing 40, with the resultant sequential movementof the parts thereof as illustrated in FIGURES a-10c, or by manipulationof the combination disk assembly mechanism by means of the combinationdial 39 and dial housing 40 in accordance with a predeterminedcombination, with the resultant sequential movement of the parts thereofas illustrated in FIGURES 2, 3, and 4.

The unlocking operation of the padlock by means of the key-operatedmechanism is as follows:

Upon insertion of the proper key into the key-slot 252 in the outerkey-slotted end 44 of the lock 42, and upon rotation thereof in aclockwise direction, as viewed in FIGURE 1, the inner pinion gearsegment 256 is caused to rotate from its normally inactive positionshown in FIGURE 8a to that shown in FIGURE 8b, in which latter positionthe gear teeth 260 of the pinion gear segment 256 are brought intooperative meshing engagement with the gear teeth 262 of the internallytoothed gear 264. Continued rotation of the pinion gear segment 256imparts rotation to the internally toothed gear 264, which istransmitted through the hub portion 266 thereof to the squared outer endportion 270 of the combination disk assembly supporting and keyactuating shaft 72, which, in turn, acting through the flattened angecollar 130 thereof, rotates the vane catch control cam carrier body 140in a clockwise direction, through an angle sufficient to bring the vanecatch control `cam 144 into lifting engagement with the lower side ofthe catch tab member 126 on the outer end of the vane catch lever 114.The vane catch 124 and catch tab member 126 is thereby lifted fromhooking engagement with the gate dog 102 of the gate vane member 100,shown in FIGURE 2, to the unhooked portion shown in FIGURE 10a. Pivotalrestraint of the gate vane member 100 is thus removed and continuedrotation of the vane catch control cam carrier body 140 eventuallybrings the control pin 146 thereof into engagement with the side of thegate dog 102, thereby swinging the gate vane member 100 from theposition shown in FIGURE 10a to the sloping position shown in FIGURE10b, in which latter sloping position the lower end of the gate dog 102is removed from a position of blocking abutment with the peripheries ofthe combination disks 162, 166 or 170.

The gate vane member 100 having thus been moved from a verticalposition, as shown in FIGURE 10a, to a pivotally displaced, slopingposition, as shown in FIG- URE 10b, pivotal motion of the locking boltlever 84 is no longer blocked thereby, and the locking bolt lever 84 istherebyvfreed for pivotal displacement about bolt lever pivot pillar 68in a clockwise direction. Thus, upon applying force of the shackle 30,tending to move it outwardly to an extended, unlocked position, suchforce is transmitted from the projection 65 at the lower end of theshackle arm 32 to the beveled surface 106 of the lock tongue 103,thereby pivotally displacing the locking bolt lever 84 from the positionshown in FIGURE 10b to that shown in FIGURE 10c, thereby withdrawing thelock tongue 103 from the lock notch 62 and freeing the shackle 30 to bemoved to its unlocked, extended position as illustrated in FIGURE 10c.

Following the before-described key-actuated unlocking procedure, when itis desired to re-establish the locked condition of the lock mechanism,force is applied to the shackle 30 in a direction to move it to itsretracted position, and, in so doing, the lower beveled end surface 66of the shackle arm 32 is brought into engagement with the lower beveledsurface 108 of the shackle arm receiving recess 104, whereby, as aresult of sliding movement between the beveled surfaces `66 and 108, thelocking bolt lever 84 is caused to pivot about the bolt lever pivotpillar 68 in a counterclockwise direction from the position shown inFIGURE 10c, back to that shown in FIGURE 10b.

The locking operation is then completed by rotation of the key in thelock 42 in a direction opposite to that of the unlocking procedure;namely, in a counterclockwise direction, thereby imparting rotation,through the combination disk assembly supporting and key-actuating shaft72, to the vane catch control cam carrier body in a counterclockwisedirection sufficient to move the foot member 128 from the position shownin FIGURE 10b into engagement with the side of the gate dog 102, asshown in FIGURE 10d, whereby the gate vane member 100 is restored to itsvertical position, followed by return of the vane catch 124 of the vanecatch lever 114 into the hooking engagement with the gate dog 102, shownin FIG. 2.

The unlocking operation of the padlock apparatus by means ofmanipulation of the combination lock assembly is as follows:

Rotation of the graduated combination actuating dial 39 and dial housing40 is transmitted through the radial coupling pin 222 to the combinationdial coupler member 208, and thence through the coupling tabs 200, 202,204, and 206 of the combination disk driver coupling member 160, andthence through drive pin 182 to the first combination disk 162. Uponsuch rotation of the first combination disk 162 in a predetermineddirection, the combination disk drive pin 186 is brought into drivingengagement with the combination disk drive pin 188 of the secondcombination disk 166, which is thereby, in turn, rotated sufficiently tobring the combination disk drive pin 190 of the second combination disk166 into driving contact with the combination disk drive pin 192 of thethird combination disk 170, which, in turn, by reason of the combinationdisk drive pin 194 also rotates the Scrambler cam annulus 172 therewith.Following such rotation of the rst, second, and third combination disks162, 166 and 170, as before described, the combination dial housing 40is then adjustably rotated in opposite, alternate directionssequentially through predetermined rotational angles as indicated by thecombination dial 39, in accordance with the predetermined combination,as is well known in the combination lock art, which results inrotationally moving the combination disks on the hub 148 sequentiallyinto such positions as to bring the gate notches 163, 167, and 171thereof into simultaneous axial alignment with one another immediatelyopposite and in engageable alignment with the lower end surface portionof the gate dog 102, as illustrated in FIGURE 4. The gate dog 102 isthen free to move downwardly into engagement with the thus aligned gatenotches 163, 167, and 171 to the position illustrated in FIGURE 3, andpivotal motion of the locking bolt lever 84 is thus no longer blocked bythel gate vane member 100, and the locking bolt lever 84 is thereforefree for pivotal displacement about bolt lever pivot pillar 68 in aclockwise direction. Thus, upon applying force to the shackle 30,tending to move it outwardly to an eX- tended, unlocked position, suchforce is transmitted from the projection 65 at the lower end of theshackle arm 32 to the beveled surface 106 of the lock tongue 103, aspreviously hereinbefore described, thereby pivotally displacing thelocking bolt lever 84 from the position shown in FIGURE 4 to that shownin FIGURE 3, thereby removing the lock tongue 103 from the lock notch 62and thereby freeing the shackle 30 to be moved to its unlocked, extendedposition as shown in FIGURE 3.

Upon movement of the shackle 30 to its extended, unlocked position, asshown in FIGURE 3, the stop knob 56 at the lower end of the shackle arm34 is moved up into the shackle guide bore 52 to some such position asshown in dotted lines therein, thereby removing the stop knob 56 fromrestraining engagement with the actuator foot 238 of the Scrambleractuator lever 232, thereby, in turn, permitting the Scrambler actuatorlever 232 to pivot in a counterclockwise direction under the force ofthe Scrambler actuator spring 240, from the position shown in FIGURE 2to that shown in FIGURE 3, at which latter position the hook portion 246of the Scrambler actuator spring 240 moves up over the edge of theScrambler cam lobe 174 into a position of engagement with the upper end17 5 of the cam lobe 174.

Following the beforedescribed unlocking operation of the apparatus bymeans of the manipulation of the combination lock assembly, when it isdesired to re-establish the locked condition of the padlock mechanism,extended force is applied to the shackle 30 in a direction to move itfrom the position shown in FIGURE 3 to its retracted position shown inFIGURE 2. In so doing, the lower beveled end surface 66 of the shacklearm 32 is brought into engagement with the lower beveled surface 108 ofthe shackle arm receiving recess 104, whereby, as a result of slidingmovement between the beveled surfaces 66 and 108, the locking bolt lever84 is caused to pivot about the bolt lever pivot pillar 68 in acounterclockwiseV direction, from the position shown in FIGURE 3 back tothe position shown in FIGURE 2. The gate vane member 100 and gate dog102 are thereby lifted upwardly out of engagement with the gate notches163, 167, and 171 of the combination disks 162, 166, and 170, from theposition shown in FIGURE 3 to that shown in FIGURE 2, therebyrotationally freeing the combination disks 162, 166, and 170 forrotation on the hub 148.

In thus moving the shackle 30 from its extended, unlocked position, asshown in FIGURE 3 to its retracted, locked position, as shown in FIGURE2,V the stop knob 56 is moved downwardly out of the shackle guide bore52, from the position shown in dotted lines in FIGURE 3 into engagementwith the actuator foot 238, thereby pivoting the Scrambler actuatorlever 232 in a clockwise direction from the position shown in FIGURE 3to that shown in FIGURE 2, thereby causing the Scrambler actuator spring240 to pull downwardly through its hooked portion 246 against the upperend 175 of the Scrambler cam lobe 174, thereby imparting a snap-actionrotational displacement of the Scrambler cam annulus 172 and the thirdcombination disk 170 coupled thereto, thereby displacing the gate notch171 from its previous alignment with the gate dog 102. The re-entranceof the gate dog 102 into any of the gate notches of the combinationdisks is thereby immediately precluded, thereby blocking any possiblepivotal return movement of the locking bolt lever 84 from its locked toits unlocked position. Any immediately following unlocking of thepadlock, without complete repetition of the combination manipulation, isthereby prevented.
